CAUTION:
Always use and hold firmly the side handle or spade
handle. This is a high-torque drill: always hold it with both hands
when operating. The side handle screws into the large hole in the
top of the tool.
Switch
To turn the tool ON, depress the trigger switch. To turn the tool OFF,
release the trigger switch. (See Figure 2).
The toggle switch above the trigger is the
reversing switch
. Switch
this toggle only when the tool is not running or coasting. After reversing
operations are completed, switch the toggle back to forward position.
To lock the tool ON, depress the trigger and push in the
lock button
.
Then, while holding the lock button in position, gently release the
trigger. To release locking mechanism, depress trigger fully, then
release it. Do not lock the switch ON when drilling by hand so that you
can instantly release the trigger switch if the bit binds in the hole. The
locking feature is for use when the drill is mounted in a drill stand or
otherwise firmly held. THE LOCKING FEATURE IS NOT FOR USE
WHEN DRILLING BY HAND. Be sure to release the switch lock button
before disconnecting the tool from the power supply. Failure to do so
will cause the tool to start immediately the next time it is plugged in.
Damage or injury could result.
For reversing operation, turn the tool off and wait for it to stop coasting.
Grasp the reversing ring (Fig. 3) and turn it counterclockwise until the
raised indicator aligns with the word REVERSE.
Chuck
To insert bit,
open chuck jaws by turning collar with fingers and insert
shank of bit about 3/4" (19mm) into chuck. Tighten chuck collar by
hand. Place chuck key in each of the three holes and tighten in
clockwise direction. It’s important to tighten chuck with all three holes.
To release bit
, turn chuck key counterclockwise in just one hole, then
loosen the chuck by hand.

screw head.
5. Remove screw by turning clockwise (left-hand thread).
6. Place key in chuck.
7. Using a wooden mallet or similar object, strike key sharply in a
counterclockwise direction (Fig. 4). This will loosen chuck so that it
can be unscrewed by hand.
Drilling
1.Always turn off tool and disconnect from power supply when
attaching or changing bits or accessories.
2.Use sharp drill bits only. For WOOD, use twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use high speed steel
twist drill bits or hole saws. For MASONRY, such as brick, cement,
cinder block, etc., use carbide-tipped bits
3.Be sure the material to be drilled is anchored or clamped firmly. If
drilling thin material, use a “back-up” block to prevent damage to the
material.
